ORGANIC CHEMISTRY LANEY COLLEGE CHEM 12A Chapter 2, Learning Objectives and Terminology Gain an understanding of the concept of orbitals ( ψ ) as a description of the regions about an atom or in a molecule where electrons are likely to be found. Other significant details about orbitals to understand are the concepts of phase , probability density ( 2 ), and nodes . Nodes occur when the probability density of an orbital reaches zero or where the phase changes – these are regions within a particular orbital where electrons are not likely to be found. Nodes can be planar or spherical (or even elliptical). Show the general shape of s , p orbitals and the hybrid orbitals, sp , sp 2 and sp 3 Construct hybridized orbital through the linear combination of atomic orbitals (LCAO) method. Link the geometry of bonding to the hybridization of the central atom involved in bonding. Bond angles represent inter-orbital angles. Apply the basic principles of
